【应用】优恩半导体推出DC24V电源的静电放电及雷击浪涌PCB空间最大化设计方案

时间： 2022-05-20 来源：优恩半导体

技术问答

在便携电子不断进步优化的时代，对防护元器件的要求也同样在提高，不仅仅是要有效防护，还需要元器件在有限的电路空间内应用，并能达到同样的防护效果。优恩半导体一直专注于半导体元器件行业，是电路保护整体解决方案供应商，经过多年经验的累计，在应对DC24V电源静电放电及雷击浪涌过压防护上，通过不断测试开发出的高通流TVS管得到了有效验证。本文优恩半导体将为您介绍DC24V电源的静电放电及雷击浪涌PCB空间最大化设计方案。

方案介绍：

此方案采用贴片陶瓷气体放电管 UN2E5-90LSMD及高通流TVS管UNS2K30CA做保护，在满足防护需求下，最小程度的占用PCB宝贵且有限空间。

产品图片：

方案符合IEC 61000-4-2 Level4 静电放电及IEC 61000-4-5 Level 4雷击浪涌测试标准，应用图示如下：

DC24V电源的静电及雷击浪涌过压防护方案是针对电源在实际应用中较远距离的传输、复杂的电磁环境，导致设备及易遭受静电或其它感应过电压等情况的影响而造成损坏作出的一份方案，高通流TVS管具有导通电压精准度高、响应速度快、钳位电压低，让后端的电路得到有效的防护，GDT陶瓷气体放电管前端泄放浪涌产生的大电流。
